TO WHOM IT MAY CONCERN:

Be it known that I, DAVID M.- REYNOLDS, of Port Deposit, in the county of Cecil, and State of Maryland, have invented certain new and useful Improvements in Automatic Lubri at rs; and I hereby declare the following to be a full, clear, and exact description of the same, reference heinghad to the accompanying drawings, in which Figures 1 and 2 are sectional elevations of my improved lubricator, showing the same in two dilerent modifications.

The object of my present invention is twofold: first, to provide suitable mcansof preventing the impurities of the oil from coming in contact with the journal or other parts of machinery to be lubricated; and,

second, to provide suitable means of regulating the quantity of oil to be discharged and used for. git en time,

To this cilect, my invention consists, first, in the employment, in combination with the oil-vesseh'and arranged in the bottom thereof, of an internal chamber or receptacle, so that the sediment or other impurities of the oil shall collect around said chamber, and prevent it from passing through to thejonrnal, as hereinafter set forth; second, in the employment in the oil-vessel, and in combination with the said chamber or receptacle, of a fibrous or other suitable filtering-substance, for the purpose of filtering the oil before it passes to thejour nal or other part of the machinery to belubricated; third, in the employment, in combination with a lubricatcr constructed in the manner as herein described, of a disk. loosely fitting the inner chamber, v'rhethcr perforated or not. provided with a regulating-screw, so that the filtering-medium may be more or less compressed, thus regulating both the supplyof oil and the density of the filtering-medium. i

To enable others to make and use my said invention, I will now describe the manner in which the same is;

or may be performed.

The lubricator, constructed in accordance with myinvention, is composed of an oil-reservoir, II, which may be made of glass. as shown in fig. 1, or of metal, as shown in fig. 2, and may be made of spherical, cylindrical, or other convenient form. The opening on top is closed by means of a cover or cap, C, which may be fitted by means of a scr'etv or friction. At its lower end it is provided nith a tapering supply-tube, I, which may be inserted in a corresponding opening in the boxes, so as to deliver its oil upon the journal. 'ithin the reservoir, and immediately over the supply-tube, there is a chamber or receptacle. I of cylindrical form, and of such a height a to only receive within it oil free from sediment, which is deposited in the bottom of the oilrcscrvoir, around the said chamber. In the axis of b th the oil-reservoirs and the internal chamber is held, by means of brackets, D. inst either to the'chanrbcr I), as :llOWll in fig. I, or to the re ervoir R, as shown in 53.2 a screw-threaded rod. 5, provided at the bottom with a dish. K, which loosely fits the internal chamber 11. By means of a thumb-piece, II, this dish may be worked up and down in the chamber. To the disk. at its under side, may be attached a pad, composed of sonic flexible and fibrous substance. whichclo' cly fits the cylindrical chamber B. It is through this fibrous substance that till oil must pass before it enters the suppiy-pipe, and

thus becomes filtered and purified before it pas c to the journal, Instead of the pad, or in addition thereto, fibrous or filteringmaterial. F, may be placed in the bottom of the chamber or Well.

It will be understood that when the oil-reservoir i fill: l with oil, by first removing the cap C, the heavier and importparticles in the oil will soon settle in the b itzn J the reservoir. and the lighter or pure oil will flow into the chamber or well B, where it will filter through thefibrous substance, and pass into the tube P perfectly pure.

To regulate the supply, and also more or less CLHi'lLllrL' the filtering-material, it is only necessary to screw the disk down, more or less compressing the fiItering-mbstancc. In order to entirely shut off the'supply oi'oil, the (lhli must be screwed on tight, or the supply-pipe may be provided with a cock or other means for stopping the flow of oil.

Having thus described my said invention, what I claim, is-

The employment, in combination with the oil-vessel, having arranged in the bottom thereof an internal with a regulating-screw,

, an" s Q a chamber or receptacle, so that tho mliment or other impurities of the oil shell collect aronnd aid chamber, of

a fibrous or other suitable fihering-lubsunce, together the whole being so lfl'tngud within uid internal chamber thut the filtering-medium maj be more or less compressed, thereby regainin both rho lnpply of theoil and the denlity of the fifieringmedium, substantially no herein It forth.

In testimony whereof, I have uigned my none to this lpecificntion before two ln'bscribing witnesses.
